Hey guys,
 
I'm in a pickle.  I finished my Bijou about a month ago and I'm without a good DAC currently, and I'm VERY close to finishing my Opus + Ballsie build.  The last thing I have to do is figure out how to wire the toroidal transformers from Twisted Pear. 
 
Can someone help me understand how to wire a transformer to the Ballsie, and how to wire a transformer to the Opus board?
 
Datasheet for tranny's is here:

Opus: http://twistedpearaudio.com/digital/opus.aspx
 
 
Thanks!

What power supply boards are you using? And what's your wall AC voltage?
 

 

[wdahm519]

Bipolar PS board for the Ballsie, and Low Current Dual PS board for the Opus.  Both of these boards are Twisted Pear boards.  AC is US standard 110/120V.

110V to transformer
 - live --> blue + violet
 - neutral --> grey + brown
 
transformer to LCDPS / LCBPS
 - AC-in 1 --> orange, yellow
 - AC-in 2 --> red, black

Nevermind, you're not talking about output transformers

 
I am confused why you even need the ballsie Lite.
 
Shouldn't you be able to do Balanced to unbalanced conversion using the transformers alone?
This is what gigawork "Big DAC" owners have done.

A true lifesaver!  Thanks man.
 
EDIT:  I just wanted to say that this allowed me to finish my DAC today so thank you.
